A bicycle wheel has a diameter of 64.0 cm and a mass of 1.80 kg.Assume that the wheel is a hoop with all the mass concentratedon the outside radius. The bicycle is placed on a stationarystand, and a resistive force of 120 N is applied tangent tothe rim of the tire. (a) What force must be applied by a chainpassing over a 9.00 - cm - diameter sprocket to give the wheel anacceleration of 4.50 rad/s2? (b) What force is required if youshift to a 5.60 - cm - diameter sprocket?
